Consider the circuit shown in Figure P11.2. Assume gm = l.0mA/V. Assume the input signal voltages are v1 = 0.7 + 0.1 sin ωt V and v2 = 0.7 − 0.1 sin ωt V. (a) Determine the signal voltages (i) vo1, (ii) vo2, and (iii) vo1 − vo2 (b) Using the results of part (a), determine the small-signal voltage gains (i) Ad1 = ∆vo1/∆(v1 − v2),(ii) Ad2 = ∆vo2/∆(v1 − v2), and (iii) Ad3 = ∆(vo1 − vo2) /∆(v1 − v2).
